TYPEWBITERFTYPE SOLDEBING AND ALIGNING APPARATUS.

Application filed August 15, 1921. Serial No. 492,516.

To all wiwm it may concern:

Be it knownthat I JOHN B. GRIFFIN, a citizen of the United States residing in Newington, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Ty ewriter-Type Soldering and Aligning pparatus, of which the following is a specihcation.

This invention relates to means for fastening typeheads to the type-bars of writing machines.

Heretofore the t pe-bar and type-head have been closely tied together and then secured by solder, the position of the type itself being dependent u n the accuracy or inaccuracy of the typear construction; and the matter of accuracy of the type-im pressions has been left for the subsequent care of the expert aligner. If the type-bar is originally bent a little to one side or the other, or twisted, or too short or long these defects will produce inaccurate an misaligned t pe-impressions, and the impressions of t e individual type will be uneven. Skilled labor has been requisite for the soldering, and more highly skilled labor for twisting, bending, shortening, lengthening and other manipulation of the type-bars, to bring the types fixed thereon to print in exact ali ment, also to make each t e level, so at it will print evenly or be on its feet. One of the most serious di fiiculties arises from the unevenness of the type-impression, and this fault is frequently accompaniediwith lack of vertical alignment, and in some cases with faulty lateral alignment also; these troubles being aggravate where each type has more than one typleface, as is the custom. It is one aim of t e present invention to minimize or avoid these difiiculties and ex edits the operation and reduce the cost of effecting the attachment and alignment of the ty es; and to this end one of the features of t e invention consistsin fixin the type-heads upon the type-bars in the rst place in their final print ng s1- tions, even though the type-bar tips temselves may be a little out of true in various ways; wherebyvery little attention is subsequently needed from the skilled aligner, thus enabling him to turn out many more machines in a given period, and expediting the work, as well as increasin the factory output. The types may be rapldly attached to the type-bars in this accurate manner, and the need for-skill is reduced, and the cost is low. To accomplish these ends, two of the obstacles to be overcome are, first, to locate the type with a super-accuracy heretofore unknown in this art, and to do so cheaply; and second, to fix and maintain this super-accurate relationship of the ty to the platen or the (printing point of tii: machine, notwithstan ing the great variety of inaccuracies usually existing in the typebars upon which the t pes are soldered, and the consequent variation in their printing positions.

The invention is illustrated in connection with the type-bars of the well known Underwood portable typewriter, in which frontstrike type-bars are pivoted in a slotted segment. The invention is preferably practised after the segment, with the type-bar blanks pivoted thereto, has been assembled in the frame-work of the ty ewriting machine. The typewriting machine in unfinished condition is accordin ly mounted in a soldering ji and the typers are swung, one after anot er, to the positions which they occupy in the ty writing machine when the types strike on t e paper, or, in other words, to their printing positions. In this illustration each pivoted ty e-bar or blank consists of-a thin lade of s set-metal, and the ti s of these blades all occup substantially tie same position when at t e printing point. They are therefore swung one after another to bring their tips or free ends to this common position. Arran ed at this central point is a soldering jig 1n which is cradled a typei This type, by the use of gages, is located at the exact position (relatively to the framework of the typewriter) that it is to occupy when printing on the work-sheet in the completed typewriter. That is to say, the type is exact up-and-down or wer tical alignment and is also in exact sidewise alignment; and is also precisel level or (units feet. The type is locate or finally and permanentl aligned and trued up in his manner ,w ile unconnected with its t .tivpe-bar. While the type is thus held, in-

e endently of its type-bar, in this precise re ationship to the typewriting machine, the selected type-bar is swungto cause its tip to enter a lon itudinal slot, groove or depression forme in the back of the type; and

while in such position the slot in the type is ill! filled up with the solder, whereby the type is finally attached to the type-bar.

One of the features of the invention, in the preferred manner of practising the same, resides in making the type-slot oversize. The type-bar tip does not fill the slot of the type, suflicient clearance bein left to allow for sli ht inaccuracies in t e form or position 0 the type-bar itself or of the tip thereof, and the two parts being rigidly connected by the solder m this relation, so that the type-bar, although out of true or not positioned with high accurac with respect to the type in the jig, is still enabled to carry the type to its exact intended position against the platen of the t pewr ting machine. This feature is valuab e not only in respect to the up-and-down alignment of the type-impression, where a variation of even one-thousandth of an inch is objectionable and not only in regard to the exactness of the lateral positions of the type-impressions, but also in regard to the evenness of each impression. Inasmuch as, according to the resent invention, each t e is itself gages to precisely the right position in the ig, the type-bar tips ma occupy other than their true ositions in e slots, which they do not fil Allowance is made for the variations in printing positions of the different t pe-bars, the misfit between the typebar an the t pe being taken u or compensated for by the solder, which 5 ls the slot the type and holds the two together in their relative positions, whatever the may be, even though the bar may be itsel a little to one side or the other relatively to the slot in the type, or even though the bar may be aLtrifie twisted, since the unequal or uneven spaces around the type-bar in the slot of the type are all filled up by the flowing solder. Hence, even though the type-bar blank may be imperfectly formed yet the impression of the type on the wor -sheet gives no evidence of such imperfection or, in other words, the result is a type that is correctlivl mounted in every way on the type-bar, wi reference to the platen not yet p aced 1n the machine, but upon w ch the type is designed to strike.

Owin to such accurate universal reparatory an independent ga 'ng of sec type in the jig in the precise sol ermg position that is occupied b all the other types, it that, upon an sequently testing or 0 rating the fimshed typewriting mac ine, t e type impressions are found to be even and also in exact ali ent in every way; or at least this man t is so closely approximated that but little remains to be done he 0nd inspection and touching up of a typeat here and there.

Previousl to placing the typewriter in the solderiiig fixture, the t e-bai's or blanks themselves may be y placing in a suitable jig the unfinished typewriter, containing the type-bar segment, and by bringing the tips of the bars one after another to a slotted central gage. At this time the type-bars may be individually adjusted by ending them to one side or the other, or by twisting, shortening, len henin or otherwise treating them in or er to bring the tips to the proper fit in the slotted gage. This fit should be comparatively close. This treatment of the type-bars is relatively simple and inexpensive, as comared with correspondin treatment of the are as heretofore practised after the attachment of the types to the type-bars. Moreover, in this pre aratory treatment the type-bars do not nee to be treated with the exquisite delicacy or skill that has been necessary heretofore in ali ning all the types after attachment. A sight latitude may be allowed in fitting the type-bar into the slotted ga e, so as not to render said fitting objections ly expensive. It may be erformed by comparatively unskilled la r; and such discrepancies as may exist in the positions of the tips of the type-bars are compensated for or taken up as the type-bars are soldered to the types One of the valuable features of the invention resides in the method employed in positioning the type in the soldering jig with accuracy in respect to the framework of the typewriting machine and therefore in respect to the platen which is subsequently to be mounted upon said framework. The t e itself is smal and frail, and presents culties when attempting to locate it in a jig with the requisite exactness, and without reliance upon highly-skilled, slow and exensive labor. In dealing with this problem, instead of attempting to set the t itself up against vertical, lateral and love in fixed ga es, it is temporarily set into a crad e. In or er to secure the requisite accuracy, the cradle has preferably a matrix, in which the type-face is laced. The matrix may correspond exact y with the type-face, whereby exact positioning of said type in every way on the type-head is mechanically determined. The cradle, with the type so located therein, may then be easily and correctly positioned in the jig by means of fixed gages, so as to bring the type carried by the cradle $5 to the exact required position corresponding with the printin position of the same in the typewriting mac me. For readily and accurately positioning the cradle, it is made of ample dimensions, and is preferably in the form of a relatively heavy plate.

The type is clamps to the gaging cradle by means of a device which insures accurate relationship between the type-head and the cradle. This clamp comprises opposin cheeks between which the type is inserts: The sides of the type-head are slightly beveled, and said cheeks are correspondingly formed, so that the type is sure to come to a seat when ressed in between said checks. The type is inserted face down in this seat, so that the slotted back of the tv e lies uppermost, for convenience in soldbring the type-bar in the slot. The clamp is provided with a screw point which bears against the cradle and clamps it against the type. The axial line of this clamping screw is perpendicular to the type-face, and said line is central of the type, so that upon turning the screw the type-face is forced to fit accurately in the matr x ortion of the cradle. Hence when the cra le is subsequently placed in the soldering jig, it results that the face on said ty e is in exactly the right position relative y to the type-segment or to the framework of the typewriting machine. Since said clamping screw point is midway 0f the type considered both longitudinally and laterally, it results that as the screw is tightened the cradle ma be settled or rocked thereby about both its ongitudinal and lateral axes until exact seating of the typefaces into the matrix is insured. The cradle, with the type and clamp both attached thereto, forms a unit which is then placed in the jig, and there held during the operation of soldering a t pe-bar to the type.

Other features an advantages will hereinafter appear.

Figures 14 an 15 show in plan and front elevation a gaging jig for aidin in effecting a preliminary truing up 0 the typebars; this fixture being the same in all respects as that seen at Figures 1, 6 and 7, except that in place of the type-soldering jig there is substituted a 'slotted gage into which to fit the tips of the type-bars; the slot in this gage being preferably a little narrower than the slots in the types.

The Underwood portable typewriting machine comprises an inner framework 10 and an outer framework 11 fixed thereto. The inner framework may be used for aging the'typewriter upon the soldering xture. Flat sheet-metal type-bars 12 swing in radial guide-slots 13 in a segment 14, the latter fixed upon the typewriter framework. So long as the types are accurately gaged, it is nctnecessary in all cases to gage the typebar systemrby means of another portion of the typewriter. It will be observed that the type-soldering jig has means to connect it with the ty e-bar system. This means comprises, in his form of the invention, a bedwork or fixture to which are attached the soldering jig and also the typewriter framework having the type system mounted therein. The type-bars swing upona curved pivot wire 15, and their tips are formed with heads or ribs 16 to be set into longitudinal slots 17 formed in the backs of types or type-blocks 18, the latter having on their faces the usual type-faces 19 in relief, and said slots being preferably oversize.

Said tw writing machine is usually provided with four rubber feet; but for the purpose of this invention there may he ate tached four temporary gagin studs 20, to serve in place of said ru her cat, for locating the typewriter frame with the requisite accuracy upon the front face of an upright table or tablet 21. This table is shown bolted at 22 to the face of a plate 23 carried upon a pedestal 24, which may be's'ecured u on a work bench. The curved fulcrum wire 15 of the type-bars has an oblique position in the typewriter; and said tem orary studs 20 insure that said segment she I have the proper obliquity relatively to said table 2]. The typewriter frame is also otherwise correctl located with reference to said table. he details of the means for locatin and retaining the ty writer upon sai table 21 will presently described.

Also carried by the pedestal 24 is a bed 25 upon which the type 18 is supported, face down, during the soldering operation." The bed 25 is referably horizontal, and the position oft e ty e at the soldering operation is also prefera 1y horizontal, and accordingly the machine-gaging table 21 of the jig is inclined a little rearwardly or to the right from vertical position, as at Figure 1. At Figures 1 and 6 the type-bars 12 and types 18 are shown both occupying their rmting positions in the tilted typewriter. t will be understood that the type-face when at the printing point is inclined rearwardly when the typewriter is viewed sidewise in normal position; and the type 18 is accordingly supported in its printing position upon the solderin bed 25 in precisely the correct relationto t e ty ewriter frame.

The soldering bed 25 may be supported by means of a frame 26 extending upwardly and forwardly from a flange 27 that is secured b bolts 28 to a downward extension 29 of ta 1e 21, said flange 27 being fitted to the surface of said table, so as to give the soidering bed 25 the requisite angle tothe ta e.

Upon the soldering bed 25 is mounted a type-carryin slide 30, whose side edges 31 are confined y plates 32, the latter secured by screws 33 to the bed 25. This arrangement permits the slide to be pulled forward from soldering position, for convenience in inserting the type units. The slide may be guided for horizontal movement or parailel with the face of the type 18, but other constructions and mountings of the type-carrier may be adopted.

The cradle to which is temporaril attached the type, for the pur ose of ena ling the latter to find its so dering osition quickly and accurately, is designa as 34, Figure 10, and preferably consists of a block, late, chase, frame or other mount. This b ock may be rectangular throughout, and is accurately finished, so that it may be readily positioned on the bed 25by means of gages, which will presently be described.

Preferably the upper face of the cradle or gaging-block 34 is formed with letters or characters 35, to form a matrix, into which fit the faces 19 of the type, which are individual to that cradle; each cradle preferably having a diflerent matrix from the others. When the type is pressed to its seat in the matrix, it necessarily results that the type is accurately located upwardly or downwardly, and sidewise, and also brought to a level, relatively to the cradle, and hence relatively to the gages against which the cradle is set, and hence relativel to the typewritin machine which is rigi 1y connected to the jig structure.

Thetype and the cradle or mount may be held together by means of a clamp, the latter seating the type in a manner to secure super-accurac and to insure parallelism of the typeace with the under or gxaging side of the cradle or gaging-block.

t Figure 13 the cradle or block 34 is seen to occupy a position between a point 36 of a clamping screw 37 and a type-holder which comprises opposing inclined cheeks 38, 39, formin a. seat for the beveled type 18. The bevefing of the type is indicated at 40, Figure 8, and the type-en aging cheeks 38, 39 have corresponding ob iquity 41. The type is brought to a seat between said jaws and firmly clamped by the screw 37 The upward pressure of the screw point 36 against the cradle, block or mount 34 not on y firmly seats the type between the cheeks 38, 39, but also secures the accurate engagement between the block 34 and the type-face 19 that has been mentioned. Said point 36, as will be seen at Figure 8, exerts upward pressure in a line 42 perpendicular to the type-face and etiuidistant from the sides of the type 18, as we 1 as from the ends thereof, so that relative rocking or skewing of one side of the type away from the mount or chase is prevented, and a. level relationship is insured. Subsequent accurate pos1tioning or gaging of the cradle therefore insures a like accurate positioning of the type in the soldering jig.

The type, its cradle, and the clamp which holds them together, form a unit which is bodily inserted in the soldering jig. Said unit is set into place upon the portion of the ji which consists of the slide 30. The ends of the cradle or gaging-block 34 rest upon four separated gages in the form of studs 43, which are now tpreferably equidistant from the type 18, an also preferably equidistant from a transverse line 44 which intersects the center of the type-head 18. These gage-studs 43 are placed at points remote from the type, so that if there should be any inaccuracy in the height of any of the studs, there will be less inaccuracy in the variation of the type itself from a true level position. The necessity of bending,

twisting and springing the type-bars to bring the types on their feet is largely eliminated. Said studs may be correctly made and set, so that they lie in the same horizontal plane, and hence the cradle or gage-block 34 may rest correctly upon all four of them, being firmly there held by spring tongues 45, the latter secured by screws 46 upon studs 47 rising from the bed plates 32 at the sides of the slide 30. These spring tongues may engage the plate 34 as it is advanced upon the slide 30, and thereby be caused to hold down said plate firmly upon the gages 43 during the soldering ogeration. Said tongues are preferably mi way between said studs at each side of the jig, in order to insure constant firm contact of the gage-block 34 on all said studs throughout the soldering operation.

It will also be perceived that the cradle or ge-block, with the type and clamp fixe thereto, occupies a position between guide-posts 48, which constitute gages to prevent endwise play of the crad e. Two pairs of studs 49 also form gages to revent play of the cradle and type in a direction longitudinal of the type. The type is so located with the aid of these gages that the necessity of subsequently lengthening, shortening or sidewise bending of the typebars is practically avoided. The springs 45 may have flaring edges to permit the gageblock 34 to advance thereunder; or the advancing edge of the block may be slightly beveled or rounded, as will be understood, to slip under the springs.

The aforesaid clamping screw 37, Figure 8, is threaded through a single jaw 50, which co-operates with the palr of checks 38, 39, forming the opposite member of the typeand-cradle clamp, Figure 13. Said cheeks 38, 39 may be carried on op osite separated arms 51, which may be U-s aped to give clearance for the block 34. Said arms 51 are separated so as to leave a clear passa e for the type-bars to swing into the slots 1n the types, said slots being exposed for this purpose. To afford a supportin means for the cheeks 38, 39, so that they wi not be excessively spread as the type-head is forced up between them, and to permit fine adjustment of said cheeks towards each other, there may be provided a clip 52, having 0 posite clip members 53, between which the c eeks 38, 39 are placed. A set screw 53' is provided in each clip member 53, and these set screws are turned in to bear against the outer faces of the cheeks 38, 39 to support them as the type is forced to its seat between them. These screws permit adjustment so as to force the cheeks 38, 39 to approach more or less, to regulate the. ex-

tent between which the ty 18 can be forced up between said chee s; but in this case the position of the type in the jig depends upon its close contact with the cradle. which in turn is accurately positioned in the jig.

In mounting the rip-ended typewriting machine upon the soldering fixture, its forward temporary feet or aging devices 20 rest directly upon the ta le 21, while the rear temporary feet 20 rest upon slide 54. which is mounted in a guiding groove 55 in the front face of table 21, for adjustment horizontally endwise or to left and right: the typewriter frame having its keyboard end uppermost and being connected to said slide to move therewith. The slide is provided near its ends with a pair of horizontal gaging abutments 56, against which rest the rear edges of sheet-metal lates 57. which form the opposite side-wa ls of the inner framework 10 of the typewriter. By

this means the typewriting machine is gaged and supported vertically. One of the abutments '56, preferably that at the right hand. is also provided with a ga e stud 58, against which 15 gaged laterally the righthand side wall 57 of said inner framework. Hence. by means of the studs 20, the gaging abutments 56 and the lateral ga ing stud 58, the typewriter is ga ed exact y with reference to the type-so dering jig or bed 25.

so that the type-bar segment 14 in the typewriter occu we a true position relatively to the set 0 gages on the soldering bed 25. or the tyipe-carrying slide 30 thereof. Thus a high egfee of accuracy is secured; and soldering t e types to the type-bars in this manner 1s found to result in practically perfeet type impressions being made on the work-sheet, with practically perfect alignment.

In order to set the slide 54 a little to the left or right for the purpose of gaging. the type-bar segment 14 into exactly central position, a nut 59 may be turned forwardly or backwardly upon a threaded stud 60, fixed to the table 21 by means of a pin 61; a com pression s ring 62 tending to return or move the side to the right against nut 59. This compression 5 ring occupies a seat 63 in the edge of the tails 21, and bears against a flange 6% turned back from the end of the slide 54.

For aiding in bring the typewriting machine to exact position in the soldering fixture, and holding it there during the soldering of the types seriatim, there may be emloyed a draw-spring 65, which extends rem a stud 66 on the rear of the bed 21, and has a hook 67 to catch over the front bar 68 of the other frame work 11 of the typewriting machine, thereby holding the forward feet 20 of the typewriting machine down upon the bed. e spring extends diagonall at Figure 1, and therefore also tends to hold the typewriter frame down or back against the gage studs 56, which support it.

Ill

I crepancies can be overcome b justment of the screw 77; an the bolts 28 This effect is augmented by another drawspring 69, which extends from a stud on the ri ht-hand end of the slide and has a hook I to catch over the right-hand sidewall 57 of the framework. This sprin 69 is doubly diagonal, and therefore hol the rear typewriter feet down upon the table 21, and also holds the frame down against the adjacent gage abutment 56, and also towards the right against the aging stud 58. There may also be provide an op site diagonal spring 72 at the opposite si e of the typewriting machine, to extend from a fixed stud 7 3 to catch over the ty writer framework, and hold this corner 0 the machine down upon the table 21 and down against the lefthand abutment 56. The spring 72 should be of lighter tension than the sprin 69, so as not to overcome the tendency of t is latter to draw the typewriter frame to the right against the gaging stud 58. The slide 54 may be held in its iideway by means of bolts 7 4 and washersg5; the bolts extending through longitudinal slots 7 6 in the slide, and being threaded into the table 21.

For securing up-and-down adjustment or gaging of the so dering jig or the bed 25, the base 27 whereof rests upon the face 21 of the main table, there may be em loved a screw 77, threaded into a hole 78 in t e lower edge of flange 77, and prevented from moving endwise by means of a fork 79 fixed by a screw 80 a 'nst the lower edge of extension 29, said ork fitting between collars 81 formed upon the screw. By turning the screw 77, a fine adjustment may be secured of the type-soldering jig to raise and lower the same, and hence gage the type 18 held thereon to precisely its printing height, which is a matter of importance in causing the type to print evenly or levelly upon the work-sheet. It will be understood that if the type-bed 25 should be gaged too high, the bar 12 would not have to be swung so far in order to reach the type. words, the stroke of the type-bar from normal position to solderin ition in the soldering apparatus, wou d shorter than its subsequent printing stroke in the finished typewriter, and hence the type-face, when printing, would lie at an angle to theplaten, and hence one edge of the type impression would appear heavier than the opposite edge. A corresponding defect would appear if the type-bed 25 were too low. These dishold the type-soldering jig wherever ad'- justed by the screw 77. Such adjustment is in a direction about vertical to the face of the type held in the jig,

After the t pe while old in horizontal position is sol ered to the t e-bar, the type clamping screw 37 is wit rawn, thus releasing the type-cradle 34 from the type,

In other delicate adand also releasin the type from the seat 38, 39, so that slide 30 may be pulled forwardly and the type clamp withdrawn from the jig, and replaced by another unit comprising a different ty and its cradle with the same or another c amp. Thereupon the slide or type-carrier 30 may he pushed backward] until a stop 82 fixed upon the front end thereof engages an ad'ustable screw stop or ga e 83, threaded into the front edge of the ed 25. This gage 83 may locate the slide 30, and hence the cradle or gageblock 34, in exact position in the jig in a direction lon itudinally of the type, or about vertical y of the table 21, that is, towards and from said table. When it is in its soldering position, the t e extends about vertically to the table. e slide may be held against the gage 83 by meansof an arm 84 pivoted at 85 to the bed 25, and held by a s ring 86 against the front edge of the sli c; said arm having an anti-friction roller 87 to run upon the bottom and the front edge of the slide. The stop 83 has a shank 88, which is secured in the slide 30 by means of a pin 89. p

At Figures 3, 4 and 5, are illustrated diagrammatically and in an exaggerated manner, im erfections in the forms of the typebars, w ich are usually the result of the processes of manufacturing and handling the bars. Owing to these im erfections, the bars or blanks are presented inaccurately to the types as the latter are held exactly in printing osition in the soldering jig. The

slots in t e type-bars are made over-size, to permit the type-bars to enter the slots in an unsprung condition, that is, in exactly the positions which the type-bars will occupy when subsequently printing upon the worksheet. The discrepancy between the imperfecttype-bar and the perfectly gaged type is taken up by the solder at 90. This solder compensates for imperfections of every kind, whether consisting of a lateral bend in the type-bar, as at Figure 3, or a twist, as at Figure 4, or a misposition of the bar, as at Figure 5, as well as for discrepancies produced by a combination of two or more of these and other usual defects. 1

At Figures 14 and 15 is illustrated a moth 0d of giving the type-bars or blanks a preparatory truing up. This shows a jig or fixture similar to that shown at the other figures of the drawings,.except that in place 0 the type-cradle there is employed 9. ga e 90 having aslot 91, whose position is he same on the general fixture as that occupied by theslot of the type at the other views. This gage slot 91, however, is preferably ama. fit closely to the gage 3 at. The typewrfter frame may be placed in this fixture at'Figure 1, and the type-bars 12, one after little narrower than the slot in,the t pe, so that the type-bar when properly ad usted spectivel another, may be bent, twisted, and otherwise brought to position to move with suitable free om into and out of the narrow ga e slot 91.

A type-aligning apparatus comprising means to gage a type-bar system, a set of similar individual matrix-blocks, each comprising a broad plate having a rectangular form for gaging purposes, and a soldering jig comprisin a single set of gages to co-operate witi said blocks one after another, each block being removable to give place to a succeeding block upon said gages, means to hold each type and block in gaged position whilethe type-bar is soldered thereto, said set comprisin rests laced close to the edges of the bloc the atter being of mammoth dimensions, as compared with the type, and its sides and ends forming gages, and said block having a matrix-face, and means to press the type into the matrix, securing microscopic leveling of the type by reason of the comparatively great distance between said blocksupporting rests, as compared with the width and height of the type.

87. The method of attaching and aligning the types of a type-bar typewriting machine, comprising providing the types with overwidth slots, and holding the types seriatim in accurately leveled and accurately gaged vertical and sidewise alignment and accurately leveled at the printing point of a typewriting machine, while the type-bars are inserted 'seriatim in said slots, occupying therein various inaccurate positions due to their various imperfections, but without filling said slots or displacing the types, and filling up the remaining space in the slots with solder, to secure the t pe, standing perfectly aligned and leve ed at the printing point, to the type-bar which may stand in slightly inaccurate position or imperfect condition at the printing point. whereby, when each ty e-bar is subsequently operated, it will bring its type back to exactly the same perfect printing position vertically, laterally and levelly.
